To all whom it may concern:

Be it known that l, WILLIAM F PALMEJL'ER, a citizen of the llnited States, residin at lElrnwoo'd, in the county of Cass and of Nebraska, have invented certain new and useful Improvements in Mixing Apparatus, of which the following is a specification.

This invention appertains to improvements in mixin apparatus generally, and more particular y to a type thereof adapted for the mixing of cement or the like for use in building operations of various classes and descriptions.

'lhe principal object of the invention is to provide for an apparatusof the class mentioned, and one of a mechanically-refined construction and arrangement, such as will render the same readily portable from one point of use to another, durable and etlicient under any and all conditions of its operation or use, and comparatively inexpensive to manufacture.

Another object of the invention is to provide for a miner of the type as hereinbefore characterized, and one involving an operating means designed to impart a continuous action or rotation to the mixer proper, re-

hill

gardless of its position of adjustment and use, and in a manner to be substantially smooth and even in its operation, and practically' free from all vibrations such as otherwise causes undue wear and tear. on the parts thereof.

'With the foregoing and other equally im portant objects in view, the invention resides in the certain novel and useful con struction and arrangement of parts as will be hereinafmr more fully described, set forth in the appended claim, and illustrated in the accompanying drawings, in which 2- Figure l is a side elevation of a preferred embodiment of the invention,

Fig. 5 is atop plan view of the container or mixer, per se,

Fig. 6 is a fragmentary vertical section taken on the line ti-tl of Fig. 4:, and Fi 7 is a similar section taken on the line 7 of Fig. l.

Referring to the drawings, wherein similar oharactersof reference designate corres onding parts throughout the several views thereof, the main frame of the mixer is preferably formed of a suitable length of etal stock bent substantially [Ll-shaped to provide oppositel forming stan connected horizontal portion or base 11. To the outer sides of the standards 10 and 10 disposed vertical leg portions are bolted, as at 12, supports 13, which have which are retained in position by means of cotter pins or the like 16. Bolted as at 17 to the base llof the main frame and immediately inward ofthe opposite ends thereof, are the free ends with respect to the opposite leg portions 18, 18, of the inner yolre shaped portion of a tongue 18, which has its outer end extended laterally in opposite directions to provide a hand gripping portion 19. lhe forward end portion of the tongue 18 is angularly bent in a downward direction, to have the hand gripping portion 19 thereof rest on the ground, when the main frame is disposed in its operative posi tion, i. e. slightly inclined from the perpendicular. Disposed within the til-frame is a substantially ll-shaped brew member, and which has its opposite leg portions 20 and 20 secured at their upper ends to the standards l0 and 10 by means of bolts or the like 21, and the lower portions thereof bolted as at 22 medially of the base ll of the main frame. Eiecured at these upper ends to the standards 10 and 10*, by the bolts 2i, are forwardly projecting inclined brace members 23 and 23., which are secured at their lower ends, by means of the bolts 2a, to the opposite leg portions 18 and 18?, respectively, of the yoke shaped inner portion of the tongue member 18. These brace members 23, 23", are adjustable and thefadjustment is had by means of spaced openings 23" being provided in their lower ends for selected engagement on the bolts 24:.

The upper ends of the standards 10 and 10- are formed to provide enlargements in the form of open bearings 25 and 25', in

the former is journaled a short pintle 26 and in the latter a bearing sleeve 27, the pintle 26' and sleeve 27 provided means for pivotally supporting a substantially til-shaped tilting frame, which is formed from a length of flat metal stock bent to provide oppositely disposed leg ortions 28 and 28" and a curved base 28. File leg portions 28, 28" at their ards 10 and i0, and a lower "lit till

lower termini, are tortionally twisted, so that they will be disposed in spaced parallel relation, one with respect to the other. This tilting or pivoted frame normally depends within the main frame from the pintle 26 and the sleeve 27, the pintle 26 being rigidly secured in right angular relation outwardly of the upper end of the leg port-ion 28, while the upper end of the leg portion 28 is formed with a circular opening loosely fitting on the bearing sleeve 27. This bearin sleeve 27 forms a housing for the journa ling therein of a power shaft 29, on the outer end of which is keyed a power driven pulley 30, and on the inner end thereof is similarly keyed a worm gear 31, which is arranged 111 mesh with a worm wheel 32 keyed on the upper end of a vertically disposed shaft 33. This shaft 33 is 'journaled in a housin portion 34 carried vertically of the pivote frame in parallel relation to the leg portion 28" thereof. The worm gear 31 and the worm wheel 32 are housed in an enlarged inner end portion 27' of the bearing sleeve 27, and to which the upper end of the housing portion 34 connects, while the lower end of the latter is secured as at 34 to a bracket 34 attached to the base 28 of the tilting frame. The upper end of the shaft 33, is journaled in a bearing plug 35, threaded into an opening formed in the upper side or end of the housing portion 34. The lower end portion of the shaft 33 is journaled in a bearing collar or bracket 36. Keyed on the lower end of the shaft 33 is a beveled gear 37 arranged in mesh with a second beveled ear 38, which is keyed on one end of a iorizontally disposed shaft 39. One end of the shaft 39 is journaled in a bearing sleeve 40, and at its other end in the end wall of a housing 41 the latter incloses the shaft 39 and into one end thereof extends the bearing sleeve 40. That end wall portion of the housing 41 which supports one end of the shaft 39 being preferably in the form of a removable plug like body substantially as shown, Fastened on the opposite end of the shaft 39, is aworm gear 42, arranged in mesh with a worm wheel 43 carried at the lower end of a mixer container operating shaft 44. This shaft 44 is journaled at its lower'end in a bearing block 45, secured in position on the base 28 of the pivoted frame, and at an intermediate point, in a bearing 46, formed at the upper side of the housing 41, and bolted as at 47, to a cross bar 48, disposed horizontally between the lower ends of the leg portions 28' and 28" of the pivoted frame 28, and is secured thereto by means of bolts or the like 49. The upper end portion of the vertical shaft 44, projects for a distance above the bearing portion 46, and extends upwardly through the concentric aperture of an external boss 50, formed centrally of the bottom wall of the mixing of the segment 58.

container 51, the latter being preferably of barrel-like form and open at its upper end substantially as shown. The extreme upper end of the shaft 44 terminates inwardly of the upper open end of the container or mixer 51, and has bolted thereto as at 52, a plurality of downwardly inclined brace rods or bars 53, which are secured at their lower ends to the inner face of the container as at 54, adjacent the bottom thereof. The upper end of the shaft 44, has secured thereto a series of radially disposed mixer arms or rods 55, which are inclined slightly in an upward direction and are secured at their outer ends to the inner face of the container or mixer in any suitable manner. It is to be noted of the housing portions 27, 34 and 41, that the same entirely enclose the shafting for transmitting power from the pulley 30 to the mixing shaft 44, and that the space therein may be filled with a lubricant entirely surrounding the gear mechanism.

The pintle 26 which is journaled in the standard 10 is formed to provide a squared outer end portion 26 on, which is engaged a hand lever 56, for effecting the desired swinging movements of the frame 28, to move the container or mixer 51 to and from operative and dumping positions. The inner end of the hand lever 56 is formed with a hook portion 57, engaged over a. half moon segment 58, bolted as at 59, on the outer side of the upper end rtion of the standard 10 immediately be ow the bearing portion 25 thereof. Pivoted as at 60 outward ly of the hooked end of the lever is a locking dog 60, which is operable through the medium of a push rod 61, disposed parallel to the lever with its upper end portion engaged for movement longitudinally throu h a hand grip 62 carried at the outer end 0 the latter. The locking segment 58, is provided with notches 63, spaced along its outer or lower curved edge for the engagement therein of the dog 60, whereby the mixer 51 may be held in any one of its several positions of operation.

In the operation of the device as thus constructed and arranged, the same may be readily pulled or pushed from one point to another by the operator grasping the handle portion 19 of the tongue 18, and, when properly positioned, the pulley 30 will be belted to a suitable source of power (not shown). When positioned adjacent the point of use, the materials for the cement mixture will be placed within the container or mixer 51, inwardly of the open end thereof, and preferably with the container or mixer disposed in its unlocked and vertical position, which position it will naturally assume when the dog 60 is disengaged from oneof the notches The container will then be swung to one of its inclined positions and locked therein by the dog 60 engaging ueaeea in one or the other, of the notches of the segment 58, after which power will be applied to the pulley 30 for the rotation of the container or mixer 51.- When the mixing operation iscompleted, the mixed cement or other material will he readily dumped from the container'or mixer 51, by

the operator grasping the hand lever 56,-

and swingin theframe and container or mixer carried thereby on the axis formed by the sleeve 27 and the pintle 26, for the tilting of the container to a position whereby the contents will readily discharge from the open end thereof.

From the foregoing, it will be readil ap- M parent that the invention provides or a of the invention, or the-scope of the claim ap ended hereto.
